It makes me appreciate a song so much more when I can see the words in front of me and listen. also helps if the song has background vocals you never could make out that end up being your favorite once you find out what they are. my favorite example of this right now is bodys (2011) by car seat headrest!
Not necessarily the lyrics, but the way the lyrics are being sung. It takes time to really hear the lyrics, so I think I have to be a little bit in love with the singer first.
